Abstract
An algorithm for the automatic parallel generation of threedimensional unstructured grids based on geometric domain decomposition is proposed. A software package based on this algorithm is described. Examples of generating meshes for some application problems on a multiprocessor computer are presented. It is shown that the parallel algorithm can significantly ( by a factor of several tens) reduce the mesh generation time. Moreover, it can easily generate meshes with as many as 5 x 10(7) elements, which can hardly be generated sequentially. Issues concerning the speedup and the improvement of the efficiency of the computations and of the quality of the resulting meshes are discussed.
